grubinstall is a simple program with clear documentation to take the mystery out of the GRUB boot loader. It installs GRUB in an especially simple, robust, hard-to-screw-up form: in a dedicated contiguous boot area at the beginning of the boot disk. This is in contrast to the tools in the GRUB package, which get filesystems involved.

Fritz!WRT is a set of patches to make the OpenWRT
trunk run on AVMs Fritz!Box. Much progress has
been made in recent OpenWRT revisions in the AR7
port, but it's still not running on the Fritz!Box.
The patches also have the potential to make the
T-Com SpeedPort run, because its hardware is very
similar to that of the Fritz!Box. There are
patches for the bootloader, LED support, and
watchdog support, as well as KGDB support.

Supervisor is a client/server system that allows
its users to control a number of processes on
UNIX-like operating systems. It also provides an

processes are started or stopped.

CD Linux Server is an embedded Linux system on a
bootable live CD. It can be used to set up mail,
Web, file, FTP, proxy, DHCP, DNS, MySQL, LDAP, and
other services very quickly. The mail server
includes antivirus, antispam, and mail recorder
features. It can be used for free for up to 10
accounts, while the advanced version is licensed
for an unlimited number of users. There is not any
restriction against the time.

SoL (Server optimized Linux) is a Linux distribution completely independent from other Linux distributions. It was built from the original source packages and is optimized for heavy-duty server work. It contains all common server applications, and features XML boot and script technology that makes it easy to configure and make the server work.

Initng is a full replacement of the old and in many ways deprecated sysvinit tool. It is designed with speed in mind, doing as much as possible asynchronously, and using the system resources more efficiently.

genext2fs generates an ext2 filesystem as a normal
(non-root) user. It does not require you to mount
the image file to copy files on it, nor does it
require that you become the superuser to make
device nodes.

rEFIt is a boot menu and maintenance toolkit for
EFI-based machines like the Intel Macs. You can use it to boot multiple operating systems easily, including triple-boot setups with Boot Camp. It also provides an easy way to enter and explore the EFI pre-boot environment.
